MouseWheel does not work when setting an HtmlSource.

Observed when the input mode is TimePicker.

ActiveDocumentEditorChanged is not always fired correctly.

1. Create a raddocking control inside of a radwindow.
2. Add a few docks.
3. Drag a dock and drop it in a floating position.
4. Drag another dock.
5. As you drag the 2nd dock the first one disappears. It's somehow falling behind the raddocking control.

There is an easy workaround - show the window in the Loaded event handler.

When the IsHidden property of Pane is set to true at startup the Pane is shown and immediately hidden.

MapPolyline (Informationlayer) or PolylineData (VisualizationLayer) disappear on higher zoom levels.

The origin of this issue is that Silverlight has limitation for the size of the polyline objects. Once this limit is reached, the calculations are wrong and the polyline is displayed incorrectly.

Possible workaround could be adding multiple smaller polylines / lines instead of one big polyline with many intermediate points.

While the SelectedItem is not null setting it to null and then returning the SelectedItem causes the drop down of the control to be opened

Any errors related to the image, however, cause the ImageFailed event from the UriImageProvider.Image property to fire repeatedly and never stop. This has been caused by 404 File Not found errors from missing images and also by a strange issue with Internet Explorer where large PNG images sometimes won't show.

Workaround:
Remove the image provider that works incorrectly using the Image.ImageFailed event.

RibbonView: RadRibbonButton has inconsistent pressed/focused state

The styling in the controls vary when the mouse is down.
- RadRibbonButton gets a black border.
- RadRibbonSplitButton gets an dark orange border (when clicking the dropdown button)
- RadRibbonDropDownButton gets a grey line at the top

On mouse over
- RadRibbonButton and RadRibbonDropDownButton have a dark orange border with a white inner border
- RadRibbonSplitButton (dropdown button) does not get the white inner border

Reason for declination: 
Currently there is no way to unify the pressed state of these buttons because there is no Pressed state of RadSplitButton (the toggle and button parts has their own press visualization that comes from the default style of the corresponding buttons). 

All attributes for table cell are exported to HTML regardless of whther they are added to HtmlExportSettings.PropertiesToIgnore or not.

Even if a cell is aligned to center or right, the td element in the HTML has attribute align="left". The paragraph within has the proper alignment, but this is confusing.

MS Word omits the align attribute of the cell and sets alignment on the paragraphs directly.

Occurs for properties of paragraph like alignment or ListId as well.

This is only happening for Appointments in the future or in the past.
